DRAFT-EQUALIZER.

SPEGIFICATION forming part of Letters Patent No. 506,844, dated October17, 1893.

Application filed March 16, 1893. Serial No. 466.349- (No model.)

To all whom it may concern.-

Be it known that I, DANIEL F. COLE, a citizen of the United States,residing at Wellsborough, in the county of Tioga and State of.

- single or double tree may be attached.

In the accompanying drawings forming part of this application: Figure lis a perspective view of my device secured upon a wagon, with adouble-tree attached. Fig. 2 is a similar view showing the devicesecured to a double-tree. Fig. 3, is a perspective View of the toothedplate. Fig. 4, is a perspective view of the toothed adjustable plate,with one of the set screws and washers.

The same reference letters denote the same parts throughout the severalfigures.

The toothed or corrugated plate A, has a series of set screw holes a,and at either end is secured by screws B to the wagon axle O, orpreferably set into the front of the doubletree D, leaving the teeth orcorrugations b, projecting beyond the surface of the doubletree.

The adjusting plate E, has upon its inner face like corrugations orteeth 0; a central projection F upon its outer face, and its arms Grhave each a slot f extending from said projection nearly to the end ofthe arms. Through these slots f and into the set screw holes a, extendthe set screws H having a washer g, the edges thereof being cut away ath' for the purpose of allowing the adj ustable plate E to be moved uponthe set screws, the entire length of the slots. The teeth orcorrugations in the two plates being of exactly the same caliber, theymesh and are held firmly together when the set screws are screwed up.When it is desired to move the adjusting plate to either side beyond thelimit of the slots, the set screws have simply to be changed to anotherset of set screw holes in the plate A. The hammer bolt I is insertedinto a hole in the projection E so as to connect a single or double treeto the adjustable plate. It will be observed that the adjusting platecan be moved to either side of the center of the plate A, by simplyloosening the set screws, and still mesh with the teeth of said plate.And that by forming a series of set screw holes in the plate A, theadjusting plate may be moved still farther to either side by replacingsaid set screws.

I am aware that it is not broadly new to employ with a draft equalizer,two toothed or corrugated plates and cause the teeth of each plate tomesh together, and I therefore do not claim any such broad idea, but

What I do claim, and desire to secure by Letters Patent, is-

1. In a draft equalizer, the toothed plate provided with a centralprojection, and having a slot formed upon each side of and adjacent tothe said projection, combined with the toothed plate having a series ofset screw holes adapted to register with said slots, and means forsecuring the two plates adj ustably together, as set forth.

2. In a draft equalizer, the toothed plate having a series of set screwholes, and means for securing it to a double-tree, combined with the adjnstable toothed plate having slots, and the set screws extending throughsaid slots, and into the said holes, substantially as and for thepurpose set forth.

In witness whereof I hereunto set my hand in the presence of twowitnesses.

DANIEL F. COLE.
